MIT, PASSUR Study Shows Significant Benefits of Surface Departure Metering Estimated Annual Savings: 14,800 Fewer Hours Taxiing, Resulting in $10MM-15MM in Lower Fuel Costs and a Reduction of 48,000 Metric Tons CO2

STAMFORD, Conn., Sept. 1, 2011 /PRNewswire/ -- The Massachusetts Institute of Technology (MIT) has released a detailed study on the significant fuel and carbon reduction benefits of surface departure metering at JFK International Airport. The departure metering program at JFK is a collaboration among the Port Authority of New York and New Jersey, the FAA, the airlines operating at JFK and PASSUR Aerospace, under the overall leadership of the Port Authority of New York and New Jersey.

The MIT study compared taxi out times, fuel burn, and emissions before and after the implementation of the metering program, based on data gathered over six months of operation of the departure metering program at JFK, which was compared to twelve months of operational data before the program was implemented. Highlights of the results are:

  • Lower fuel bills for airlines: an estimated $10MM-$15MM annual savings across all the carriers involved in the metering program (using a range of $2-$3/gallon cost of aviation fuel), due to the "engines off virtual queue." Per-carrier savings will vary depending on their actual proportion of the schedule and fleet mix.
  • Greener operations: 5 million fewer gallons of fuel burned per year, resulting in a reduction of 48,000 metric tons of CO2 emitted into the atmosphere per year, derived from "engines off virtual queuing."
  • Improved passenger experience: 14,800 fewer total departure taxi hours per year, resulting from flights that remain at the gate with passengers in the departure lounge (or sometimes at a remote metering pad) followed by a lower active taxi time when they are released, rather than joining an extended active taxi queue.

The proprietary program uses a combination of software, process management, and a manned operations center staffed by a PASSUR professional services team to create a "virtual departure queue" in which departures are "metered" by holding flights either at the gate or in a common metering area, rather than queuing in an extended line of aircraft with engines on. Once aircraft enter the active taxiway, they are ready to depart quickly, in a shorter taxi queue with less fuel burn. "Virtual queuing" ensures that a flight's position in the departure line-up, and its planned runway departure time, are both preserved, even though the aircraft is not physically out on the active taxiway.

PASSUR assisted in the MIT study through the provision of data as well as guidance on the analytical methodology and results interpretation based on PASSUR's design, implementation and operation of the departure metering program at JFK.

The study was conducted by researchers from MIT Lincoln Laboratory and MIT's Department of Aeronautics and Astronautics who are undertaking benefits assessment of surface congestion management systems at a large number of airports in the U.S. in support of the Tower Flight Data Manager (TFDM) system being prototyped at MIT Lincoln Laboratory to help meet the FAA's Next Generation Air Transportation System (NextGen) objectives. The JFK study was also complementary to MIT's own field demonstrations of a departure metering concept at Boston Logan airport. These studies are part of a broader set of gate-to-gate operational mitigation areas under exploration, which also includes advanced departure, cruise and approach operations.

Briefing slides providing key results from the study are posted on the PASSUR website at http://www.passur.com and a technical paper reporting the detailed results of the study will be published at the American Institute of Aeronautics and Astronautics (AIAA) Aviation Technology, Integration and Operations Conference in Virginia Beach in September.
